Application October 23, 1946, Serial No. 705,068

11 Claims. 1

My invention relates to signaling devices and particularly to devices ofthis character for awakening people at any predetermined time.

In my co-pending application, Serial No. 613,070, now U. S. LettersPatent No. 2,444,748, I have disclosed an alarm clock, specifically anelectric alarm clock, by means of which two signals of differentcharacter are given in sequence. The first signal is the flashing of anelectric lamp which may continue for any desired interval and which, ifthe lamp is burned out or any other defect prevents the giving of thisfirst signal, is supplemented by an audible signal such as a buzzer.

The present invention relates to a signaling device in which the firstsignal given is a visible signal, as by the flashing of a lamp, and thesecond signal is given from a loud speaker of a radio, and in which themeans for controlling these signals is of somewhat different characterthan that disclosed in 'my co-pending application aforesaid.

One of the objects of my invention is to provide a radio receivingdevice combined with a clock by means of which the timing of thesignaling means is controlled. Another object is to provide a cabinet inwhich is combined a radio receiving means and a clock, and to which anyavailable electric lamp maybe connected by simply plugging the lampwires into a receptacle in said cabinet. Another object is to provide adevice of this character in which the radio may be used at any timeindependently of the signaling apparatus. Another object is to provide adevice in which a table or other lamp may be connected thereto and whichmay be utilized to give the flashing signal, and also used at any time,except when the signaling apparatus is in actual operation, as a readinglamp independently of the signaling apparatus. Another object is toprovide a signaling device comprising a radio receiving set for givingan audible signal and a. lamp for giving a visible signal and means forcontrolling the operation of these signals in timed relation to eachother. With these objects in view, my invention includes the novelelements and the combinations and arrangements thereof described .belowand illustrated in the accompanying drawings in which- Fig. 1 is a frontelevation view of my device;

Fig. 2 is a rear view of the device drawn to a substantially smallerscale;

Fig. 3 is a fragmentary perspective view of a portion of an electricclock with certain portions omitted and certain portions broken away inorder clearly to show the particular parts thereof and the partsassociated therewith which are pertinent to my invention;

Fig. 4 is a wiring diagram including, in a more or less diagrammaticmanner, those portions of the clock mechanism which control theoperation of the signaling circuits;

Fig. 5 and Fig. 6 show the relative positions of the contact fingers inclosing the circuits for the first and second signals respectively; and

Fig. '7 is a fragmentary wiring diagram similar to Fig. 4 butillustrating a modification of the lighting circuit.

Referring to the drawings, my device comprises a cabinet I containing aradio receiving set which may be turned on and off by means of theswitch 2 and tuned by means of the knob 3 which moves the index 4 overthe dial 5 which may be graduated in kilocycles, as well understood inthe art, to indicate the frequency to which the set is tuned. 6 is theopening of a loud speaker, understood to be in the cabinet but notshown. I is an electric clock having a hand 8 which may be turned by theknob 9 to indicate the time at which the signal will be given. Ill is aknob for turning the alarm on or off and II is a table lamp, actuated bypulling the switch cord l2, and which may be plugged into the socket oroutlet IS on the back of the radio cabinet. As illustrated in Fig. 4,the outlet l3 would have three terminals and a three wire conductorwould be required to connect the lamp II with the circuits in thecabinet in order to by-pass switch 12 when the alarm goes into operationand insure a positive operation of the lamp signal ll irrespective ofthe position of switch [2. Projecting from the back of the cabinet I isa button It by turning which the hands of the clock may be set to thecorrect time. Also extending from the back of the cabinet I is theelectrical conductor l5 having the usual plug IS on the end thereofwhich may be inserted in any convenient outlet for connecting both theclock and the radio to a source of power.

Referring now more particularly to Fig. 3, I1 is the back of the face ofthe clock. I 8 is a wide faced clock gear which is directly connected tothe hour hand and which, therefore, makes one complete rotation every 12hours. I9 is a narrow faced gear of the same diameter as the gear I! andin mesh therewith so that it also makes one complete rotation in 12hours. 20 is a gear which is connected to the spindle or shaft carryingthe alarm setting hand 8 (see Fig. 1). In mesh with the gear 20 is thegear 2| which is in mesh with the spur gear 22 on a shaft 23 which maybe turned through suitable gearing (not shown) by turning the button 9to set the alarm at the desired time. The gear wheel 2| is provided withan arcuate slot 25 therein which cooperates with a cam 26 on the rearside of the wheel I9. Since the wheel l8 revolves in the direction ofthe arrow shown thereon the wheel IS, in mesh therewith, revolves in thedirection of the arrow shown on that wheel. The wheel i9 is coaxial withthe wheel 2| and rides freely on its shaft l9 so that it may move towardand away from the wheel 2| and still remain in mesh with the wheel l8;the face of the wheel l8 being of substantial width to permit theaforesaid axial movements of the wheel i9 while maintaining it in meshwith the wheel l8. The cam 26 on that face of wheel l9 which is adjacentwheel 2| is providedwith two steps 21 and 28 positioned to drop in theslot 25 in the wheel 2|. The high point of the cam 26 normally rides incontact with the side of the gear 2| and the wheel |9 carrying cam 25 isnor mally urged towards wheel 2| by the lever 29, which is-mounted onshaft 30, and the light helical spring 3| which is biased to hold thelever 29 in contact with the hub 32 on wheel l9.

From the foregoing, it will be apparent that the gears 29 and 2| arenormally stationary except when the alarm is being set byturning thesetting button 9. 7

It will be also apparent that, since the gea l9 makes one turn in every12 hours, the cam 26 will be forced into the slot 25 once in every 12hours. First the step 2' I will drop into the slot 25 and, as the wheell9 continues to rotate, step 23 will drop into the slot. As the wheel I9continues to rotate, the cam 25 will be forced out of the slot andpushes the wheel l9 back to its normal position by the cooperation ofthe curved cam-like surface 33 with the end of the slot.

The wheels l9 and 2| with the slot 25 and cam 26 are also shown in Figs.4, and 6 in a more or less diagrammatic manner but, before passing to adetailed description of these last mentioned figures, it might be wellto point out that, in Fig. 3 an armature or buzzer 34 having a clapper35 associated therewith and adapted to strike the gong 36 is shown andmay be used if desired. The armature 34 is always energized when theclock mechanism is connected to a source of power and, unlessrestrained, would vibrate continuously. It is normally held inoperativeby means of the push-pull button 31 which projects through the back ofthe casing or cabinet I and has a projection 38 thereon which cooperateswith the armature 34, when the button 31 is pushed in, to preventvibration thereof. The armature is also restrained by the projection 38on the lever 29 when in the position shown in Fig. 3. However, when thebutton 31 is pulled out, the armature or buzzer is then held inoperativeonly by the projection 38 on lever 29 so that, whenthe cam 26 drops intothe slot 25 in wheel 2|, as wheel i9 is moved towards wheel 2| by thelever 25 and spring 3|, projection 38' moves away from the end ofarmature 34 and the armature automatically begins to vibrate and emit a.buzzing sound or ring the gong if provided with the clapper 35.

Referring to Fig. 4 in connection with Fig. 3, it will be noted that aresilient finger 39 is provided with a button 49 of fibre or otherinsulating material which bears against the side of gear l9 whichcarries the cam 26. The finger 39 is m unt d w th fin e s 42. 43. and 44on the back of the face H of the clock as shown in Fig.

4. Each of these fingers is electrically insulated.

from each of the other fingers by means of the insulating blocks 45therebetween-and the insulating bushings 43 through which the means 41for securing them together pass. The resilient flnger 39 is providedwith contacts 43 and 49 on opposite sides thereof the finger 4| isprovided with a contact 56 adapted to cooperate with the contact 48 onfinger 39; the finger 42 is provided with a contact 5| adapted tocooperate with the contact 49 and, on the other side thereof, with acontact 52 adapted to cooperate with the contact 53 on the finger 43; 43in turn being provided on the other side thereof with a contact 54adapted to cooperate with the contact 55 on finger 44.

Normally, the gears I9 and 2| and the resilient fingers are in positionshown in Fig. 4, while Fig. 5 shows the position of the fingers when thecam 28 has moved its first step into slot 25 in wheel 2|, and Fig. 6shows the position of the resilient fingers when cam 26 has moved itssecond step intothe slot 25.

In Fig. 4, 56 and 51 are the main power lines to which the terminals 58and 59 of the signaling device are connected when the plug i6 isinserted in a convenient outlet. 60 is the radio which is provided withthe switch 2 for turning it oil and on and the tuning means 3 which isregulated by the knob 3, shown in Fig. 1. It will be apparent that, byclosing the switch 2, the radio 69 may be. connected directly to thepower lines 56 and 51. Thus, by closing or openin the switch 2, theradio may be operated at any time independently of the signalingmechanism. l I is a table lamp, one terminal of which, when the lamp isplugged into the outlet I3, is connected permanently to the power line56, and the other terminal may be connected with the other power line 51by closing the switch 12 which closes a circuit through the conductorsGI and 62, and

switch l0 which is a double pole, double throw switch, or itsequivalent, for closing and opening the circuits, as shown in Fig. 4. Itwill be apparent from the foregoing that the lamp ll may be used at anytime in a normal manner when the switch I9 is in either the alarm oil orthe alarm on position.

When the alarm is set at the desired hour, the switch I0 may be moved tothe alarm on position, but this does not in any way, so long as thealarm is not in actual operation, interfere with I the normal use of theradio or the lamp ll. Thus, the lamp may be turned oil and on by meansof the switch l2 although a somewhat different circuit is used when theswitch I0 is in the on position than when it is in the off position.When the switch I9 is in the on position, the circuit through the lampis through switch I2, conductor 6|, finger 4|, through the contacts 48and 50, finger 39, conductor 64, switch l0 and conductor 63 to the mainpower line 51. Obviously, the movement of the switch ID to the alarm onposition does not in any. way affect the operation of the switch 2 toturn the radio off and on.

Ordinarily, upon retiring, the table lamp switch would be turned to theoff, position to extinguish the light but, whether or not it isextinguished, it will begin to flash, as will be described below, whenthe first step of cam 25 drops into slot 25. When this occurs at theappointed hour, and the switch it is in the alarm on position, thefingers are as shown in Fig. 5 and a circuit through the lamp i isestablished as follows:

The connection between contacts 68 and 59 is broken and a connection isestablished between contacts 49 and 5|, as shown in Fig. 5, thus theauam , circuit through the lamp control switch I! is opened and switchI2 is by-passed. Starting with power line 55 adjacent the lamp II, thecurrent flows through the lamp. conductor 35, switch I3, conductors 55and 51 through the coil 55 which surrounds the bimetallic element 59 inthe thermostatic switch 10, and thence through conductor 1|, finger 42,contacts 49 and 5|, finger 39, conductor 54, switch It and conductor 53to power line 51. When the thermostatic switch 13 is in this positionthe light H is not lighted because suflicient current is not flowingthrough the above circuit due to the high resistance of the coil 59 inthe thermostatic switch. However, the

vcurrent flowing through the coil 59 heats the thermostat element 59causing it to warp upwardly and close the contact points so that acircuit between lamp I is then established through conductor 55, theshort leg 12 of switch ill, conductors 55 and 51, the contacts of switch19, directly through the thermostat element 59, conductor 1|, finger 42,contacts 49 and 5|, conductor 54, the long leg 19 of the switch I5andconductor 53 to power line 51; and the lamp is thus lighted.

However, the closing of the contact points of switch 15 shunts theheating coil 53 around the thermostat element 59 which causes theelement 53 to cool and flex so that the switch is opened whereupon thecycle 1.; repeated. Thus, an intermittent flashing of the lamp continuesso long as the last mentioned circuits are maintained. While thethermostatic element does not entirely break the circuit through thelamp, since some small amount of current is always flowing through thehigh resistance coil 55, it does, in efiect, break the lighting circuitinsofar as the illumination of the lamp is concerned, and I havetherefore referred to its function as that of making and breaking anelectrical circuit.

When the second notch or step of the cam 25 drops into the slot 25 thefingers are then in the position shown in Fig. 6. In this positionfingers 39, 42, 43 and 44 are all electrically connected together withthe following result:

When finger 44 is electrically connected, as in Fig. 6, to finger 39, anew circuit is established through the lamp II which by-passesthermostatic switch 10 and connects lamp directly to the power lines sothat an uninterrupted lighting of said lamp occurs. Thus, starting fromthe power line 55 adjacent lamp II, current flows through lamp conductor55, the short leg 12 of switch It, conductors 55 and 14, finger 44through contacts 55, 54, 53, 52, 5| and 49 to finger 33, thence throughconductor 54 through the long leg 13 of switch iii and conductor 53 topower line 51.

Simultaneously with the uninterrupted illumination of lamp Ii, anothercircuit is established through the radio receiver 50 as follows:

Starting at the point where conductor 15 contacts power line 55, currentflows through the conductor 15 through the radio receiver 53, throughthe conductor 15 which by-passes radio control switch 2 to finger 43,thence through contacts 53, 52, 5| and 49 to finger 39 which isconnected to conductor 54, thence through conductor 54 and the long leg13 of switch Ill through conductor 53 to power line 51. Thus, ii. theradio receiver is tuned to receive a program or signals from a certainstation, the program or signals will be heard through the loud speakerof the receiver.

If the device is used as an alarm clock, the

6 oil by moving the switch III to the of! position whereupon the lightIl may be controlled by means oi! the switch I2. Should it happen thatthe signaling means has been set for operation and no one is present toshut oil the signal by moving switch III as aforesaid, the cam 25, dueto the rounded face 11 thereon will, in a short time, ride out oi theslot 25 and restore the parts to their normal position shown in Fig. 4,thus automatically shunting oil! the signals.

With the arrangement as illustrated and described in connection withFig. 4, a three-wire cable is required it the lamp I is to be controlledby a switch |2 thereon because it is necessary to have two separatecircuits, having one common wire leading to the lamp so that itis'possible both to control the lamp through the switch I2 and also tocontrol the lamp H by means of a circuit which by-passes switch l2.

Where an ordinary two-wire cableis used to connect lamp II to an outletI3 in the casing I,

a minor change in the lamp circuit is required as shown in Fig. 7, andit is also desirable to provide the switch Ill with a neutral or "offposition. The only change required in the circuit is to elimlnate theswitch l2 and to connect the conductor 5| to the conductor as shown at18 in Fig. 'I. With this circuit the lamp may be lighted by turning theswitch ID to the "light position so that a circuit is formed from powerline 55 through the lamp, conductor 5|, conductor 52, the long leg 13 ofswitch lliand conductor 53 to power line 51. To extinguish lamp II,switch I0 is merely turned to the oil position.

When the fingers are in the position shown in Fig. 4 and the switch Itin Fig. '1 is in the alarm on position, no current is flowing throughthe conductor because one of the current paths leading from conductor 55is through conductor 14 to finger 44 where it terminates, and the otherpath is from conductor 55 through conductor 51, heating coil 59 onthermostatic switch 10 and through conductor 1| to finger 42 where itends. However, when the first notch of cam 25 drops into the slot 25,thus connecting finger 42 with finger 39, a circuit through lamp I andthrough the thermostatic switch, which causes an intermittent flashingof lamp II, is established as described above: When the second step ofcam 25 drops into slot 25, thus arranging the switch fingers asillustrated in Fig. 6, the radio receiver is connected to the powerlines and the lamp II is connected directly to the power lines toproduce an uninterrupted lighting thereof, as described above.

From the foregoing, it will be apparent that the lamp alone may be usedas a signal by merely tuning the radio receiver so that no signal isreceived therefrom when said receiver is connected to the power lines.Furthermore, the radio receiver may be used alone as a signal by merelyremoving the lamp II from its socket; the buzzer or gong may be usedalone in place of the lamp, or with the lamp or the radio, or with both.

While I have described my invention in its preferred embodiment, it isto be understood that the words which I have used are words ofdescription rather than of limitation and that changes, within thepurview of the appended claims, may be made without departing from thetrue scope and spirit of my invention in its broader aspects.
